/**
* SECTION:lib_assertion
* @short_description: <lib:Assertion>
*
* <blockquote>
* Authentication assertions provided in an AuthnResponse element MUST be of
* type AssertionType, which is an extension of saml:AssertionType, so that the
* RequestID attribute from the original AuthnRequest MAY be included in the
* InResponseTo attribute in the Assertion element. This is done because it is
* not required that the AuthnResponse element itself be signed. Instead, the
* individual Assertion elements contained MUST each be signed. Note that it is
* optional for the InResponseTo to be present. Its absence indicates that the
* AuthnResponse has been unilaterally sent by the identity provider without a
* corresponding AuthnRequest message from the service provider. If the
* attribute is present, it MUST be set to the RequestID of the original
* AuthnRequest.
